EXPLOSION-ENGINE.

Specification of Letters Patent.

Patented Oct. 24, 1905.

To (Li/Z whom, i2; may concern:

Be it known that I, RICHARD H. Soon, a citizen of the United States, residing at Lansing, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Explosion-Engines, of which the following is a specification, reference being had therein to the accompanying drawing.

The invention relates to explosion-engines, and more particularly to the means employed for increasing the efficiency of the engine by the introduction of water into the heated explosion-chamber and cylinder.

The invention consists in the construction whereby a measured quantity of water is directly introduced into the heated chamber; further, in the manner in which the quantity of water introduced is regulated, and, further, in the peculiar construction, arrangement, and combination of parts, as hereinafter set forth.

In the drawing a section is shown through a portion of the cylinder and Water-jacket of an engine to which my improvement is applied.

A is the cylinder of an explosion-engine. B is a port therein for the admission of the explosive mixture and the exhausting of the products of explosion, and O is a water-jacket surrounding the cylinder. The precise construction of these parts is not essential to the present invention, and they may be formed in any suitable manner.

1) is a small conduit opening into the cylinder or into the port B, immediately adjacent to the cylinder. This conduit contains a check-valve E, slidably mounted in a suit able guide member G and arranged to close by the pressure from the cylinder and to open by the suction of the piston during the admission of the explosive charge to the cylinder. An adjustable stop-pin H of any ordinary construction is'provided to limit the outward movement of said check-valve E.

F is a valve controlling the admission of water to the conduit D beyond the checkvalve E, this being preferably a needle-valve, as shown, and having a screw threaded stem 0, which may be adjusted to variably restrict the port 5.

The water admitted through the conduit B and controlled by the needle-valve F and check-valve E may be obtained from any suitable source. For convenience I preferably draw the Water directly from the waterjacket, and to, this end the check-valve E and portion of the needle-valve F containing the port I) are both arranged within the waterjacket. The stem a of the valve extends out through the jacket and is provided with a suitable handle (Z, by which it may be adjusted.

With the construction described in operation whenever the explosive charge is drawn into the cylinder the check-valve E will open automatically and permit water to flow through the retracted port I) and through the conduit B into the cylinder. The quantity of water thus admitted may be accurately regulated by suitable adjustment of the needlevalve F, and in passing into the cylinder it crosses the path of the incoming gases and is atomized thereby. The effect of the introduction of the water in the manner described is to greatly increase the efliciency of the engine, and the quantity may be regulated according to various conditions, so as to secure the best results. heavy load, a greater quantity of water may be used to advantage than when the engine is running light.

It is to be observed that the water is introduced into the supply-conduit of the explosion-chamber at a point where the heat from previous explosions will quickly vaporize it. This prevents dangerof the accumulation of water in the conduit through which the explosive mixture is introduced into the cylinder, as would be the case if the water were introducedinto said conduit and conveyed by the explosive charge to the cylinder.

What I claim as my invention is- 1. In an explosion-engine, the combination with an explosion-chamber, of a water-jacket for the chamber, a supply-port, means for introducing the explosive mixture therein, and means Within the jacket for simultaneously injecting Water from said jacket directly into said supply-port in the path of said mixture and adjacent a heated portion of said explosion-chamber.

2. In an explosion-engine, the combination with the explosion-chamber, a water-jacket surrounding the same, a supply-port, means for introducing the explosive mixture therein,.and means within the jacket for injecting a predetermined quantity of water from said hen the engine is under jacket directly into said supply-port in the path of said mixture to cool the explosion- 1 chamber as heated from previous explosions.

said explosion-chamber, an inwardly-opening check-valve in said connection for governing the supply from said jacket, and a valve op- 5 erated from Without said jacket for variably restricting said connection.

In testimony whereof I affix my signature in presence of two Witnesses.

RICHARD H. SCOTT.
